Since the middle of 2017, the price of computer components has doubled, but the video accelerators are the most expensive. All the reason - the growing popularity of mining, it even led to a partial shortage in the market for video cards.
This year, the situation with components has stabilized. But the bitcoin rate also dropped from a record $20000 to less than $6000, after which, however, it grew back and crossed the $10000 mark. Whatever it was, mine it became not so profitable, and advertisements for the sale of "two-monthly" components began to appear on the secondary market for computer equipment.
How much can you help out by selling the average mining farm, and how much will you have to spend to build it from scratch?
New mining farm
Any personal computer starts with the motherboard. It is the one that connects the individual components together and makes them work as the user needs. The minimum amount that will have to be spent for this "miracle" of technology, was established at the mark of 30 $, the maximum - 1173 $. The difference in price depends on the manufacturer of the board and the type of socket (the socket where the processor is inserted). By the way, among the "miners" are in great demand motherboards of the middle price segment, worth about 102 $. And the main criterion when choosing a device is the number of connectors for a video card.
Total for the motherboard will have to pay an average of 102 $.
And now the video card, in the extraction of cryptocurrency, it plays the most important role, its power is measured in megacheshs. By the way, the creation of Bitcoin is built on hashing. And for comfortable earnings on the Internet, only top models of video accelerators are suitable, their total amount of video memory should be more than 10 gigabytes. How much does it cost? Quite expensive. The price of typical accelerators starts from 310 $, and ends with 2240 $.
For a mining farm, you need about 4-6 cards. The average miner spends about $ 510 on one video card, if you buy six pieces at once, you will have to fork out $ 3060. Plus to this price we add the cost of "risers" - special devices for connecting several cards to the motherboard. The price of one "riser" is $ 18, multiplying by six, we get $ 108.
In total, the purchase of six video cards with "risers" will have to spend 3 168 $.
Power supply: its power should be more than 1000 watts. The price of the device in popular online stores is different, the minimum is 82 $, the maximum is 612 $. If you buy a block for a mining farm, you have to spend 126 $.
But you can save on the processor, because its performance does not affect the speed of mining cryptocurrencies. The minimum cost of this component was set at $ 22, the maximum - $ 2694. The price depends on the manufacturer and the type of socket. For a mining farm, a $ 76 CPU is suitable.
The optimal amount of RAM for the farm - 8 gigabytes. The minimum price for this device is 89 $, the maximum price is 404 $. For the extraction of digital currency fit one bracket of RAM cost 89 $, the amount of 8 gigabytes.
The last in the list of components - the hard drive. It may be small in volume. By the way, the "miners" demand the hard "SSD" drives of 120 gigabytes. The starting price for them is 25 $, the final price is 1675 $. For a farm, a hard disk costing about 53 $ is suitable.
The final price of not the most powerful mining farm is $ 3614. The resulting figure can be called the unit profit of the company that sells you the components.
What is included in the check?
The motherboard is 102 $.
Six video cards + “risers” - 3 168 $.
Power supply - 126 $.
The processor is a 76 $.
RAM - 89 $.
Hard disk - 53 $.
The overall performance of the assembled mining farm will be approximately 169 mega-hash, and the payback period at the current rate will be more than 12 months.
By the way, there are ready-made solutions on the market. The minimum price for an already assembled mining farm with an 160 megahesh capacity is 4200 $, but it is not advisable to call the maximum price, because it may vary depending on the wishes of the buyer.
However, if the farm is not to your liking, there is an alternative option for the extraction of cryptocurrency, the so-called Asik. This is a complex technical device, which is designed specifically for mining. A distinctive feature of it is high performance. The power of "Ashik" is measured in the trash and the power of the video card in megahash, the difference in zeros is obvious. By the way, there is a "specialized miner" about 6000 $. And despite the high price, "Asik" is popular in all measure.
If you sell everything
If the mining cryptocurrency did not meet expectations, the farm can always be sold on the secondary market. However, 20% should be safely taken away from the funds spent on the purchase. We managed to find some ads for sale on the site of one of the famous online sites for the sale of second-hand items. The minimum price for a mining farm for four video cards was set at 568 $.
In the average price segment, the value of the digital currency earner ranges from 3775 $ to 6530 $. And the most expensive farm sell for 10143 $.
